the strap securely upon the device, and to' permit of a ready occasiondemands.

In the drawings,Figure 1 is a perspective; Fig. 2 is an edge elevation;and Fig. 3 is a top plan.

The device forming the subject matter of removal .of the strap when thisapplication, is a hook-shaped structure,

the longer arm of which is denoted by the numeral 1, the shorter armthereof being denoted by the numeral 2. At its extremity, the shorterarm 2 is enlarged to form a head 7, the intermediate portion of thelonger arm 1 being enlarged to form the head 8. In the head 7 of theshorter arm, there is an opening 3 disposed opposite to a similaropening 4 in the head 8 of the longer arm. A keeper 5, formed integrallywith the longer arm 1, extends across the opening 4, while a keeper 6,formed integrally with the shorter arm 2, extends across the opening 3.

The extremity of the longer arm 1 is en larged, as denoted b the numeral9. In this enlarged end 9 o the longer arm, there is a triangularopening 10, the base of which triangular opening is disposed at rightangles to the longer dimension of the device. In the end of the longerarm 1, there is a slot 11, communicating with the triangular opening 10.The axis of this slot is inclined at an angle to the longer dimension ofthe device, thus forming the points 14, disposed diagonally with respectto each other, and formed in the acute an les defined by the edges ofthe slot 11 and t e transverse bar 18 which serves to define the base ofthe triangular opening 10. A portion of the constituent material of thelonger arm 1 is struck from the apex of the trlangular opening, andpreferably bent to form the hook 12, or like strap-engaging projection.

In practical operation, one end of the strap is caught over the hook 12,the free end of the strap being passed beneath the keeper 5, and thenceextended over the bent portion 16 of the hook, the free end of the strapbeing then passed beneath the keeper 6. When it is desired to use thedevice, the free extremity of the strap is passed through the opening inwhich the strap is to be secured, the strap then being twisted slightlyand passed edgewise through the slot 11. When the strap is released, itwill untwist itself and rest against the transverse bar 18, in thetriangular opening 10.

By reason of the fact that the opening 10 is triangular in outline, thestrap, when once inserted into the triangular opening cannot well beremoved therefrom, savin by deliberate intent, since the convergingedges 20 of the triangular opening, engagin the strap, serve to make thetwisting o the strap so that the same will ass through the slot 11, amatter of consi erable difliculty. Owing to the fact that the axis ofthe slot 11 is inclined with respect to the longer dimension of thedevice, the points 14 are formed, and, should the strap accidentallybecome engaged in the slot 11, and then be drawn upon, these points 14,engaging the strap, will prevent the strap from slipping entirely out ofthe grip of the device.'

Having thus described the invention, what is claimed is A securingdevice of the character described, consisting of a hook-shaped memberhaving unequal arms, there beingtransverse keepers upon the arms and atriangular opening in the longer arm, adjacent the end thereof, aportion of the constituent material of the device being struck from oneapex of the triangular opening to forma strap-en gaging projection,there being a slot in the end of the longer arm, communicating withtriangular opening, the axis of which slot is disposed at an angle tothe longer dimension of the device.

In testimony that I claim the foregoing as my own, I have hereto affixedmy slgnature in the presence of two witnesses.
